As for how to reproduce the bug: Before Event Card Patch: 1: Speak to Eva Levante 2: Give the Ghallardoodles to Zavala through the Holiday Oven 2.4 3: Accept all other quests (Winter Night [Also breaks/doesn't progress], Cookie Delivery Quest, etc.) 4: Don't complete the other quests or have a masterworked Holiday Oven After Patch: - Go back to Eva Levante - Reclaim the first quest as it tells you Congrats! Game is broken! (Entirely) Unwanted effects: - Being unable to completely masterwork the Oven - Cannot resupply Oven with the glitch active (all characters) - Cannot proceed with any of the quests (all characters) Expected results: - Quests continue from in-game save point. - You can restock Holiday Oven materials, fully. - Other quests (such as the "Winter Night" quest) continue from the saved progress as well. Notes: I did this on a Titan through an Xbox Series S, after I purchased the new Ornament with Bright Dust. I am also the only one of my friends (that I know of) who is fully locked out of the quests, so it could be a rare bug.
